First West Nile Virus-Positive Mosquito Pool In Massachusetts Confirmed

The Maryland Department of Agriculture (MDA) announces the first state detection of a West Nile virus (WNV) mosquito pool in Maryland in 2008. State Department of Health and Mental Hygiene (DHMH) laboratory results completed yesterday confirmed the presence of WNV in mosquitoes collected by Montgomery County Department of Health personnel on July 22 and July 29 in the Gaithersburg area of Montgomery County. MDA mosquito control personnel continue to work aggressively to reduce mosquito populations across the State.

“We know that West Nile virus may be present throughout Maryland and are not surprised to find mosquitoes testing positive for West Nile virus,” says Secretary of Agriculture Roger Richardson. “The confirmation of virus-positive mosquitoes serves as a reminder to all residents to continue protecting themselves against mosquito bites and to conduct backyard mosquito control activities.”

The MDA mosquito control office, in cooperation with DHMH, is conducting state-wide surveillance activities to monitor mosquito populations and detect mosquito-borne viruses of public health concern. Surveillance activities for adult mosquitoes use traps and landing rate counts. Mosquito control activities conducted by MDA include larviciding and spray programs for adult mosquitoes in communities that voluntarily participate in the agency’s program. Additional mosquito-borne disease surveillance is conducted by the U.S. Department of Defense on military installations in Maryland.

“Mosquito control remains especially important to decrease the risk of infection with all mosquito borne diseases,” said Michael Cantwell, MDA acting chief of mosquito control. “MDA is taking appropriate steps for mosquito surveillance and mosquito control activities in participating Maryland jurisdictions through the end of September.”

Most mosquitoes do not pose a threat to public health because they are not infected with viruses or other pathogens. Less than one percent of people bitten by a mosquito carrying West Nile virus will

become ill. People most at risk for developing symptoms of the disease are those over 50 and those with already compromised immune systems; however, all residents should continue to take measures to protect themselves from mosquito bites. These measures include:

* Avoid unnecessary outdoor activities at dawn and dusk when mosquitoes are most active;

* Wear insect repellents, according to product labels, especially if you will be outside between the hours of dusk and dawn when mosquitoes are most active.

* Wear long sleeves and long pants to help avoid mosquito bites. Avoid mosquito infested areas.

* Install and inspect window and door screens in homes and stables and repair any holes found.

* Remove standing water from flower pots, tarps, trash receptacles, and other containers;

There is neither a specific treatment nor a vaccine against WNV for humans. There are, however, effective vaccines against the virus for horses, ostriches and emusBalso known as ratitesBand owners are encouraged to get their animals vaccinated and boostered in a timely manner in consultation with their veterinarian.

Comments

GenoMed, has had encouraging results treating West Nile virus encephalitis since 2003.
We’ve had 82% treatment success rate in people (23 of 28 improved), 75% in horses (6 of 8 survived), and 50% in birds (6 of 12 survived). Our first 8 human WNV patients were published in a peer-reviewed medical journal in 2004 (1), so our treatment officially exists in both the medical and legal senses.
We’ve seen that the earlier the treatment is begun, the better the outcome, so public education is key.
We’re eager to see if our approach works again this year. Anybody who wants to download our WNV trial protocol can do so for free at any time by clicking on the "West Nile trial" link on our company’s homepage at www.genomed.com.
